"Never give up because there is always something better out there if you keep trying."

"My mother was the gentlest soul - all tender smiles and wise words. I have such fond memories of her stroking my fur, and murmuring, "sow compassion wherever you wander, and ever will kindness bloom in your wake." Even now, we can not give into our fears and primal terror. We must be kind."

History

Spoiler:

A wild and free life the Plusle lived, yet she showed no sign of her enjoying it. Mois was an only child, and was abandoned by her parents in her younger years. Despite this, she showed no emotion of depression, happiness, anger, etc. Like a blank robot. To her, life was a bore, and felt like she could never make anything out of it, even if things did get better than expected. She may sound depressing, but really the blunt mood was just part of her personality. She had lived her life style in Hoenn, simply resting on a tree, glancing at passerbys with boredom. Though she had thought of negative things toward those that were simply annoying.

During her lazing days, a Minun simply strolled across her 'sacred' tree, ignoring warnings from the other local Pokemon gave him of Mois's bad attitude. The Plusle did hold a grudge against the Minun, as he attempted to be Mois's first friend. The reasons for this was unknown, except for one; He was like Mois - being abandoned, loneliness. He wanted to share it with someone.

The attempt actually took several months rather than days. Mois was annoyed with the Minun, but tolerated his company, despite stating she never considered him as a friend, it was obvious she was fond of him as well. She got used to him just tagging along and speaking of their favorite subjects.Their friendship lasted a year, Mois started smiling, removing that blank attitude she had. The Plusle became more postive, and more social, as if she was a whole new person. It was fun for her and the Minun, but it was the same year that drama between them appeared. The drama between the two ex-bestfriends was over something silly, and lasted a long time... That was until the Epidemic hit.

The Epidemic tore Mois from the Minun even more, the Plusle was devastated, for it was also the day she would tell the Minun her apology. Saddened, she took the Epidemic as a symbol for her to continue being postively strong, and to enjoy life as if it were her last day, giving her more current positive personality.

Mois spends her days during the Epidemic simply hiding in a town and quickly scurrying to the next every couple of days. She got used to the routine, as it helps avoid several undead.
